The auto washer switch input is overridden during the washer coupled wip\
er operation.
The auto washer switch input is overridden during the auto washer couple\
d wiper operation.
The auto washer switch input is overridden during the rain sensor coupled wiper or vehicle
speed sensitive INT wiper operation.
When the auto INT switch input is received during the auto washer operation, the auto washe
r
operation stops and the auto INT operation is activated.

▶Rain Sensor Coupled Wiper and Auto Light ControlIf equipped with RKSTICS rain sensor, it has following operation system.\

▶System layout

02-138710-01
Rain sensing unit
(AUTO light integrated type)
▶INT Switch Auto Position Remi nder (Power-Up Reminder Wiper)
When turning off and on the auto INT switch, the system drives the wiper motor through LOW
relay regardless of communication with rain sensor.
When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition switch in the
"ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle, regar\
dless of the rain
sensor communication.
After that, when turning the INT-AUTO switch fr om the "OFF" to "ON" position, the LOW relay
operates to drive the wiper motor for 1 cycle only if data from the rain\
sensor indicates rain drops.

Multifunction wiper switch:
AUTO and sensitivity control
A sensor that emits infrared rays through LED and
then detects the amount of rain drops by receiving
reflected rays against sensing section (rain senso
r
mounting section on the windshield) with
photodiode (auto light sensor integrated type) AUTO
: Wiper operates automatically by rain sensor
FAST↔SLOW : Auto delay/Auto speed control. A
position that can control sensitivity against rains on
the windshield and transmits wiping demand signal
accordingly

▶Washer Coupled Wiper in Rain Sensing ModeThe washer coupled wiper is operated when receiving the washer switch input with the ignition
switch and the INT-AUTO switch "ON" in the rain sensing mode. At this moment, the
communication with the rain sensor is overridden. However, a washer input is overridden if there is
an output for continuous operation.
The operation data is sent to the rain sensor even during the washer cou\
pled wiper's operation.

▶Sensitivity ControlThe wiper LOW relay is turned on and the wiper motor runs one cycle when the volume sensitivity
is increased (ex: sensitivity 0 ⇒ 1) while the ignition switch and the INT switch is in the "ON"
position, and the wiper motor is in "Parked" position). However, the wiper motor can be operated
only when the rain sensor detects the "Rain Detected" signal.
If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs
only one cycle.

▶When the Wiper Parking Signal is abnormalThe wiper system continuously outputs the wiper parking signal when the wiper parking terminal
is grounded, while the ignition switch is in "ON" position and the INT s\
witch is in "ON" position.
-
※The wiper motor runs only when the rain sensor requires the wi per operation.
When the parking terminal is fixed to IGN, t he wiper system outputs the wiper operating signal
for 2 seconds, then continuously outputs the wiper parking signal.
-
※The wiper motor runs only when the rain sensor requires the wi per operation.

▶Defective Rain SensorThe wiper relay (LOW) is turned on and the wiper motor runs one cycle when the volume
sensitivity is changed to 2 from 3 during receiving the malfunction sign\
al from the rain sensor,
while the ignition key is in "ON" position and the wiper switch is in "O\
N" position.
-
The wiper relay (LOW) is turned on and the wiper motor runs one cycle when the volume
sensitivity is changed to 3 from 4 during receiving the malfunction sign\
al from the rain sensor,
while the ignition key is in "ON" position and the wiper switch is in "O\
N" position.

Check whether the multifunction wiper switch is in the "AUTO" position.
Check the power to the sensor. Check the conditions of the pin 3 (Groun\
d) and the pin 4
(IGN).
Check the wiper relay for defective.

Symptom 2. It rains but the system does not work in "AUTO" position.
TROUBLE SHOOTING
▶
The wiper does not operate one cy cle when turning the multifunction
wiper switch to the "AUTO" from the "OFF" position or starting the
engine while the wiper switch is in the "AUTO" position.
When starting the engine with the multifunction wiper switch in the "AUTO" position, the
wiper operates one cycle to remind a driver that the wiper switch is in \
the "AUTO" position.
When the multifunction wiper switch is turned to "AUTO" from "OFF", the wiper operates
one cycle.
It always operates one cycle for the initial operation, however, the wiper does not operate
afterwards to prevent the wiper blade wear if not raining when turning the wiper sw\
itch to
"AUTO" from "OFF". However, the wiper operates up to 5 minutes after rain stops\
. If this
function does not occur, check No. 8 pin. If the pin is normal, check the wiper relay related
terminals.
1)
2)
Symptom 3. The wiper operates 3 or 4 times at high speed abruptly.
Check whether the variable resistance knob on the multifunction wiper switch i\
s set in
"FAST". The "FAST" is the highest stage of sensitivity and very sensitive to small amount o
f
rain drops. Therefore, change the knob to low sensitivity.
Symptom 4. The wiper operates continuoulsy even on the dry windshield glass.
Check the wiper blade for wear. If the wiper blade cannot wipe the glass uniformly and
clearly, this problem could be occurred. In this case, replace the wiper\
blade with new one.
Check whether the variable resistance knob on the multifunction wiper switch is set in
"FAST" The "FAST" is the highest stage of sensitivity and very sensitive\
to small amount o
f
rain drops. Therefore, change the knob to low sensitivity.

▶Auto Light ControlThe tail lamps and headlamps can be controlled by the communication with the rain sensor only
when the auto light switch is in "AUTO" position with the ignition switc\
h "ON".
-
Rain detected headlamp: If it rains heavy which requires the highest INT speed (almost LOW),
the headlamps are turned on automatically.
-
Night detected wiping: When the auto light control turns on the headlamp\
s and the rain senso
r
detects the rain, the wiper sensitivity is automat ically increased by one level in comparison with
daytime.
(i.e. the AUTO wiper switch is at the 3rd level, but the wiper operates\
at the 4th level.)

Enlarged auto light sensor
Emitter lens
The LED emitting the infrared
rays is installed on the bottom
and the lens guides the infrared
rays to target point.

▶Volume Sensitive INT (Intermittent) Wiper
For RKSTICS without the rain sensor, perform the following operation:
Controls the wiper intermittent operation by the values from the vehicle\
speed and the volume
(resistance).
-
Calculates and converts the Intermittent interv al automatically by obtaining the INT VOLUME
when the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitiv e mode when turning the INT switch to the
"ON" position with the engine running or starting the engine with the INT switch positioned to
"ON".
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds

Vehicle speed calculation
-
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
VOLUME calculation
-
The pause time of the vehicle speed sensitive INT wiper is calculated by\
the INT volume (inpu
t
voltage). Each level has the hysteresis.
˙
Pause time calculation
-
Pause time means the duration that wipers are stopped at parking positio\
n.
Elapsed time means the duration after the wiper motor started to operate from parking
position.
The pause time is calculated by the vehicle speed and the VOLUME.
※If the pause time is below 1.0 second, the wipers operate without pause.
※If the pause time is over 1.5 seconds, the wipers operate intermittently.
